- STEAM-GENERATOR.

To all whom it may concern:

device in connection with a vertical tubular boiler. Fig 2 is c section of Fig. 1 on line X Y. Fig. 3 shows two of my generators applied to an ordinary house heating boiler W ich has a Water leg or Water jacket. Fig. 4 is a section of Fig. 3 onthe line U V. In Figs. 1, 2,-A represents the ash pit, B represents the fire pot, 0 represents the brick wall, stock or supportin heating apparatus whic incloses the fire box and supports the boiler, and M represents the fire box door.

1) represents an ordinary vertical tubular boiler which rests upon top of shell 6.

The main feature of my device is the 'eneretor E. This eneretor E is a round drum 19 from whic extend four ears 10,

'11, 11 and 12. The whole drum and ears may be cast together and may be strengthsued by ribs 18. The drum 19 should be somewhat smaller than the inside of shell C as shown by the dotted lines in Fig. 2. The cars 10, 11,11 and 12 are integral with drum 19 and are hollow. They project out through well 0 through suitable openin 's therein and thereby support the drum. the center of the dens rises e sprayer 14. which is substentielly e: solid cylmder terminating in a; cone which rises close to or into an opening to at about the center of the top of the drum. flpenimrifi connects with the feed water pipe 39 "y a passage 16 throu h a member which may be cast on top 0 generator E over drum 19 end out over ear 12 as shown;

vide a. man-hole 23 in the top of boiler D and a fusible plug 24 therein if desired. Boiler. D is fed with cold water through the main feed pipe 25 and the steam therefrom passes out through the main steam pipe 26.

Near the bottom of boiler D, I connect a generator feed pipe 30 which is bent downward Well below the generator E, thence 1 upward forming a trap and into the end of passage 16. I prefer to provide an air cock 35, :1- clean out plug 36, and a clean out valve 37 in the positions shown n this generator feed pipe.

From the bottom part of ears 10 and 1'2, outside of stack C, l droplllc pipes 10, 10 and continue them in horizontal sections in which are clean out, valves" 4 2, thence upward and over into ,the side of the top of boiler B. l/Vhere pipes 40 enter boiler D fromthe side, I prefer to rivet a splash plate 47 to the top of the boiler in front of each such inlet p1pe. This is to break the force of the steam or water which passes into boiler D through said pipes. v

The operation of the device is as follows. When starting, boiler Dis filled to a. point above the fusible plug and above generator feed pipe 30 with water 50 which runs out through pipe 30 into passage 16 and through hole 15, which is made relatively small as compared with the generator outlet pipes l0. over the bottom surface of generator E. The small quantity 0' water in generator E is rapidly converted into steam and passes down and out through steam outlet pipes 40 forcing any surplus water which may collect in the pockets of outlet pipes 40 ahead of it and up into the top of boiler i). As soon as the fire is started in fire box B, on account of the relatively small size and capacity of enerator E, steam is rapidly created therein and forces the water down tbrou h the ipes :0, 40, and up into the top of boiier D.

enerator E thus clears itself and thereafter 2. relatively small quantit of water passes into it through hole 15 an is distributed by gor'ayer 14 in iv'ided condition. As generator E is di- This Water is distributed by sprayer 14 a comparatively minute and rectly over the fire, it gets rapidly very hot and the water through hole 15 is instantly converted into steam which passes down throu h steam outlets 40, 40, and intoth'e top 0' main boiler E, from whence it passes out through main steam outlet 26. As soon boiler, a Water inlet and a steam outlet as steam begins to be created in boiler D, the steam from both boilers mixes and passes out through main steam outlet 26. When generator E is once cleared, it continues to act as a flash boiler and main boiler D can be filled as full as desired and kept full, as generator E will be automatically fed only a relatively small quantity of water as described.

Figs. 3 and 4 show two of the first forms of generators applied to a water jacket boiler or water leg boiler. The main boiler H is formed with a large compartment at the top through which passes the smoke pipe 71 from fire box'N which has a fire door P. The sides extend downward and form the water legs 72. Between these water legs are four vertical slots 73 of just the width of the cars 80, 81,81 and 82 of the generators K and'L. The cars of generators K and L are slid into slots 7 3 and are then held in place at short distances apart therein by plates 74:, 7 which are secured in place by bolts as shown. The rest of the slots is then filled up with brick 7 5. Generators K, L-are thus heldin place within the legs as shown. Each generator K and L has a sprayer 1.4:, opening 15, and passage 16. Each passage 16 connects by Way of a separate feed pipe 83 with-the main generator feed pipe 30 which is attached in the same way, and bent in the same way as the one shown in Fig. 1. It has an air cock 35, clean out plug 36, and clean out valve 37 as shown. Each generator K and L has two steam outlet pipes 84:, 84 dro ped from ears 80 and 82 outside the water egs which connect with main outlet pipes 40, 40, as shown. These outlet pipes 40, 40, run as do those shown in Fig. 1 except that they enter the top of main boiler H instead of the side. Boiler H is provided with splash plates 47 as shown.

The principle of my device is to allow a small amount of water to enter slowly into a small, very hot generator which -is close to the fire, whereby the water will be turned to steam very rapidly and will be rapidly available, while the larger volume of water in the main boiler is being heated through. Be-

sides this, I utilize the radiant heat from the fire and thereby save a large amount of heat which would otherwise be wasted.

What I claim asv my invention and desire to cover by Letters Patent is 1. In a steam producing apparatus, a main boiler, a generator below the main boiler and closer to the fire, combined with a generator inlet water pipe which leaves the main boiler and extends downward and upward in U shape and enters the enerator at the top, and steam outlet pipes rom the bottom of the generator which enter the main boiler at the top. Y

2. In a steam producing apparatus, a main therefor", and a cylindrical shell by which the main boiler is supported, combined with an auxiliary generator which comprises a central drum of a size smaller than the shell and is formed with hollow supporting ears extended through said shell, a generator feed water pipe which leaves the main boiler near the bottom and extends below the generator in U shape and enters the to of the generator through a relatively smal openmg, a sprayer inside the generator, and "generator steam outlet pipes which leave the cars at the bottom form U shaped bends extend out through the shell, said steam out lets being'formed with de endent U bends and extended into the top 0 the main boiler, together with a water inlet pipe which extends from near the bottom of the main boiler and downward forming a U bend below the U bends of the steam' outlet pipes, thence upward and over into the top of the generator as described. 1

4. In a steam producing apparatus, the combination of a shell, a main boiler supported thereby, a generator with a .flat bottom smaller than the shell and located inside thereof and below the main boiler and provided with hollow ears which project through the shell, a plurality of steam outlets from the bottom of the ears of the generator outside the shell, said steam outlets being formed with dependent U bends and extended into the top of the main boiler, and a water inlet pipe which extends from near the bottom of the main boiler down ward forming a U bend below the U bends of the steam outlet pipes, thence upward and over into the top of the generator as described.

5. In a steam producing apparatus, the combination of a shell, and a main boiler supported thereby, with a plurality of generators each of which has a flat bottom, is smaller than the shell and is located inside the shell below the main boiler and is provided with hollow ears which projectthe main boiler, and a, water inlet pipe which extends from near the bottom of the main boiler forming a U bend below the U bends of the generator steam outlet pipes, 5 thence upwal rd and over in a plurality of branches one branch into the top of each generator as described.
